Is this an insult or a compliment? :D
Perhaps merely an observation.
Could we use "als", but not "eruit"?
No. 'Eruit' is part of the verb.
So why is the zien before the eruit in this sentace, why not je eruitzien als een stroopwafel?
Because it is a seperable verb. 'Zien' is the "verb part" of the verb, which takes the second spot in the sentence. 'Eruit' follows. ;)
Just a tiny detail: "separable" :)
How about "Je lijkt op..."?
"Je lijkt op een stroopwafel.", seems fine to me, you should report it.
Alright, it's accepted like that, mine was rejected because I also included "als".
Why is "jij ziet er uit... " not correct?
Unfortunately not, see the explanation from xMerrie from above. Eruitzien is the verb and you separate it like ziet eruit.
Why is "je ziet als een stroopwafel eruit" wrong?
